Displaying Videos and Images on 4Dsystems uOLED Serially

$0D = carriege return. It just move to the first column
$0A = new line. It moves to the line below.

Very likely your display works with pixel coordinate so these commands are useless.

Try reducing the delay to Find the minimum necessary for having the display working.

I did that and works, but it looks like it has a delay for displaying the lines.

I wonder if there is any other available modification on the code in order to display both.

thanks for your kind help.

ok it does not matter this a lot, i can stand with that. Now i need to create some active touch buttons on the screen. Once i manage to do it, i will let you know.

thanks.

ok lets go back to my previous question first and then i move on to the touch buttons.

first of all i have been in touch with the guys from 4D system. I have asked them how is it possible to display two line at the same time.

They told me that the display has a TX output that send to the microcontroller a signal of ACK $06.

So the microcontroller needs to wait first for the ACK and then to check the second command and display both at the same time.

Is there any example here in the forum that can guide me how to wait for the ACK of an exernal device?

I guess that has to do with serial in and serial out ports.

So what i have to do is that one i send the comand to the display, i need to wait on the RX on microcontroller the right $06. If it read that it is right then i move on the next command.

could you please help me a bit?

thanks,

use identifier WAIT(6) in your SERIN2 or HSERIN command.

If your referring to the uLCD-32PT. i recommend not use the display as a serial terminal. it has a very nice processor on board that will handle all of your touch commands. With the addition of the 4D-VISI putting graphs and buttons on the display is just simple click and drag. Of course we are talking 4DGL language, however once you have the display process the touch commands you can spit that out to serial so your pic micro can take over.. I will post my project if 4D systems ever get their freaking carrier boards in stock.
